Hello, I've been using the case files and protocol detailed in this paper for a study on nasal airflows comparing nasal resistance pre- and post-operatively.

I've run into a few doubts:

1- Are the flow rates in Figure 4 not scaled to cubic meters? I tried using the numbers shown in the figure, and my velocity values didn’t compare to the ones that were pre-set in timeSeries in your case files—until I scaled them to cubic meters, assuming the numbers in figure 4 were originally in liters.

2- Should I be wary of a high cumulative error when using your simulation? e.g. 0,1 cumulative, xe-05 per time step.

Thank you for your time.
